Acknowledgments

My first thanks goes to God for blessing me with the ability to learn and grow in any field I choose. With Him, all things are possible!

For me, it is hard to believe that I am on the fourth edition of this book. I appreciate my family and my friends, who have supported me in my publishing journey through three titles and multiple editions.

It is my hope that you, the reader, succeed in your IT certification goals!

To my beautiful wife, Nalini, and my children, Aine, Fiona, Nicolai, and Shay, I cannot thank you enough for your support and love over the years. Also, to my parents, Ted and Annette, who inspired me to be an eternal learner and try to help others to gain knowledge. I would like to acknowledge my fellow teachers who make immeasurable sacrifices to see their students succeed. My sincere thanks to all of the tremendous reviewers, editors, and other staff at Pearson who I have had the honor of working with for many years.
